FAQ of Vertical Multistage Centrifugal Pump of QDLF Series

 

1. How can I get trained on CNBM products?

Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

2. Are your pumps cheaper than those of your competitors?

CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

3. Do you have self-priming pumps?

Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.

4. Is it really necessary to fit a bleed valve for the boxes?

It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

Q:About how to calculate the pump installation height?
Best to find water pump manufacturers, their own bad count. Sometimes is not necessarily correct, which is related to some parameters of the pump itself, with bad cavitation
Q:QDX is a submersible pump. What does "X" mean?
QDX is a submersible pump model, its specific meaning is:1.Q: submersible pump.2.D: single-phase power supply, three-phase electricity is not marked.3.X: pump, pump type is not marked.Complete submersible pump model will generally add rated flow, rated lift and motor power rating. For example: QDX40-8-1.5, meaning with single-phase 1.5KW motor, rated flow of 40 cubic meters / time, the rated lift of 8 meters under the pump submersible pump.According to the different relative position of pump and motor, submersible pump is divided into pump type and pump type. The pump submersible pump motor in the above, below, this structure greatly reduces the radial size of the pump, so much for submersible pump and small submersible pump operation. Submersible pump submersible pump on top of the pump in the following, it is divided into two types of internal and external type. The submersible pump carries the liquid through the annular flow passage around the motor, then cools the motor and then flows out of the pump outlet. Even though the pump is near the drain sump, there is no need to worry about the temperature rise of the motor, so the application is becoming wider and wider. External pump submersible pump directly from the pressurized water chamber after the impeller or diffuser outlet of discharged liquid, motor is cooled by liquid pumping. As the lower pump structure can work in a relatively shallow liquid, it is often used in submersible pumps for operating surfaces, especially the main structure of large caliber submersible pumps.
Q:Difference between primary hot water pump and two hot water pump
A hot water pump is a water pump circulating between the boiler and the heat exchanger, and the two hot water pump is a circulating water pump between the heat exchanger and the user. That is, there is no relationship between a water pump and heating users.
Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
Strictly speaking, eleven kilowatts or more is not allowed to start directly
Q:Level 200 meters distance, elevation 30 meters, how much lift water pump?
According to the horizontal distance of 10 meters is 1 meters lift, 200 meters is 20 meters and 5 meters height difference of 30 Mega elbow, pump head floating down 10%, should be about 60 meters.
Q:Why does the pump decay when connected in parallel?
Because a water pump has reached the rated parameters, the parallel is only "superfluous".
Q:What is the function of the backflow pipe of the fire pump?
Generally, it is used to test the fire pump. The procedure is to start the fire pump - turn on the return pipe - return the water to the pool. The purpose of the installation is to prevent damage to the pipe caused by the excessive pressure caused by the pump.
Q:Domestic pump does not turn, but the motor is energized what is the problem?
The home pump does not turn, but the motor is energized:A: there are heard buzzing, but can not move and no death card. It is likely that the boot capacitor is broken and that the capacitor can be measured with a universal meter.Two: if the motor is sure to have electricity, check whether there is low voltage or broken phase (three-phase motor). These conditions also cause the motor not to rotate, or the speed is low (easy to block), so it should be measured with a universal meter.Three: you can smell there is no burning flavor, may be motor winding interphase short-circuit. Bearings should be hard to break, and it's probably not good to find repairs.If the capacitor is replaced, it is better to choose the same capacitor as the original configuration parameter. If the capacitor is damaged and does not know or can not see the mark parameter, it can be calculated and matched according to the following formula:In C=8JS (F), the capacitance of the C- is S- (F). The current density of the starting winding of J- motor is generally selected from 5 to 7A/ (mm) 2, and the cross section area (mm2) of the starting winding winding. Generally, you can choose 1000W/40 F.
Q:What is the relationship between pump power, lift and flow?
When the power is constant, the kinetic energy theorem is known as P=F*V, that is, W=F*S.In the water pump, it is said that the work done by the unit time pump = the gravity of the water flow * the displacement of the waterIt can be seen that:1, the power is certain, the head and the flow is inversely proportional.2, the greater the power, the greater the product of the head and flow.Therefore, when the flow is minimum, the pump head is the maximum; when the head is the minimum, the flow is the maximum.
Q:The role of water replenishing pump in circulating system
There are three ways of constant pressure in water system. 1, the expansion tank constant pressure, this method applies to small and medium water systems, low cost. 2 water pump constant pressure, the role is when the system because the water shortage during the operation, resulting in insufficient pressure, the water supply system can play the role of water pressure. 3 pressure tank fixed pressure, pressure tank fixed pressure at the same time, also need replenishment pump water, the individual feel that the first two kinds of economic reality
